Application filed September 18,1906. Serial No. 385,062.

To all whom it may concern:

lBe it known that I, JOHN J. STALDER, a

i citizen of the United States, and a resident of ful Improvements inCultivators,

. without destroying 'raised and lowered and with themvMeade, in thecounty provenient.

'of the .subframe of Meade and State of Kansas, have invented certainnew and useof which the following is a specification.

My invention relates to improvements in cultivators and moreparticularly to that class of cnltivatorsv designed to cultivate alfalfaclosely, destroying weeds, grasses, etc.,

` i the alfalfa plants.

The object of my invention is to produce a simple cheap and efficientcultivator for'the special purposes mentioned, although it may be usedfor other purposes, and to these ends itonsists in vcertain featuresof-construction, arrangement and combination ofv parts as will behereinafter fully described and pointed' out in the claims, referencebeing hadto the accompanying drawing in which Figure 1 is a sectionalelevation 'of my imf Fig. 2 is a top plan view of 3 is a detailsectional plan'view Fig. 4 is 'a section of ,the

intle of shovel beam..

e main frame A. which is Fig.

Satine.

subframe showing In the drawing t made of angle iron or steel is mountedon the' stub axles B carrying the wheels C; the frame is crossed at itscenter bythe member D which is also of angle iron and su ports at itsforward end the tongue or sha t E, and near its rear end supports theseat F and also the toothed quadrant G by means of. which and a handratchet lever H the" shovels of the cultivator may be manipulated. Fromthe main frame is suspended the sub-frame .J

which is pivoted atJ2 to the main frame at each end, and at the frontsaid sub-frame J is suspended by the screw schafts L whichv 'passthrough the main frame and have threaded thereonthe hand Wheels M bymeans of which said threaded shafts may' be the subframe J.

To the sub-frame J are attached the com.4

posite shovel beams N consisting of the side bars n diverging at theirforward ends and ivotally swung to thefront crossbar of subameJ by theintles o'riveted to the said sub-frame; the s1de bars n are held apartby a sleeve n interposed bei veen them and fitted on a bol*I n2' passingthroughsaid side bars; toward the rear of the side bars n they comeclose together extending substantially parallel and have pivoted to themthe shovel scribed; surrounding the rod above and below the thimble Sare coiled springs Z, and at the extreme upper end of said rod Q `arethe jam or lock nuts U by means of which the tension of said springs maybe regulated.

T is a rocker frame consistingr of a forward channel member Tf beforementioned and the rock shaft V supported by the main frame, and thecrank arms V which engage 'the aforesaid channel'bar T ends. The rockshaft is manipulated by the hand lever H.

To the sub-frame J at its center is secured anlevis j by means of whichthe team may be hitched to the device. .The channel member T consists oftwo shaped beams placed back to back and held together by the pintles Owhich consist of the pin'portion o which is passed through said :lshaped beams and then upset, and the pivots 0' projecting at each sideback of the channel member.

To the under side of the main frame at each end is suspended a bar VVsupporting at its lower end the axle X. upon which are wheels being solocated that there will be one walking wheel between every two shovels;these walking wheels mounted between the shovels aredesigned to forcetrash past the shovels.

The angle of the shovels is adjusted by raising or lowering sub-frame Jby means of screw L operated by hand wheel M as indi-- cated in Fig. 1.by the positions l, 2, 3.

' The depth of the shovels is adjusted bythe Ilever H mounted on therock shaft.

' AS the rods Q thimble which is bo ted to the member T of the channelframe and as the-s rings Z are mounted on said. rod above an below saidthimble, it will be seen that the depth of the shovels is controlledthrough said springs.
